PATENT THORVALD HANSEN, OF EVERETT, MASSACHUSETTS, ASSIGNOR OF ONE- HALF TO A. HUN BERRY, OF VVALTHAM, MASSACHUSETTS.

COP-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 763,882, dated June 28, 1904.

Original application filed November 20, 1900, Serial No. 37,181. Divided and this application filed January 14, 1903. Serial To all whom it may concern:

Be it known that I, THORVALD HANsEN, of Everett, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Cop-Cutting Machines, of

which the following is a specification In winding small copssay cops wound upon a cop-tube one-half inch in lengthI have found that better work is accomplished where a number of threads are wound upon a single long tube, each thread building up its own cop upon its own section of the cop-tube,

and then the cop-tribe is cut into lengths corresponding to the thickness of the cop.

In an application, Serial No. 37,131, filed by me November 20, 1900, I have shown a machine capable of winding a number of threads into a number of cops upon a single tube in the manner to which I refer, and in the same application I originally showed means for cutting such a cop-tube after it had been wound into a number of tubes, so that when, say, four cops were wound on one tube the tube should be out between the cops into four short tubes, one for each cop. The present application is a division of the application referred to and shows the cutting mechanism'therein first described.

My present invention, therefore, consists in means whereby a long cop-tube may be subdivided into a number of short tubes, and it will be understood by reference to the drawings, in which Figure 1 is a vertical section of the cutting mechanism, Fig. 2 being a cross-section of the cop and knife holder on line 2 2 of Fig. 1, showing one of the knife-blades in a cutting position and a cop-holder in position to hold the cop during the cutting operation.

It will be understood that this mechanism now to be described may be mounted upon one of the spindles of such a machine as is described in the above-named application, or it may be separately mounted and power applied to it, as may seem fit. I have shown it, however, as part of such a machine and have shown the cop tube as wound with four threads (No model.)

in the manner described in the said application.

A is a shaft made hollow at its end to form 5 a knife-holder B. Upon this shaft is a gear A, by means of which power may be applied to the shaftas, for example, by engagement with the gear F shown in my said application.

Instead of this gear A, however, a pulley may 5 5- be substituted, if thought best.

A is a housing which, with suitable bearings A for the shaft A, may be supported upon the table of the machine or in any other desired way.

The knife-holder B contains a springb and a follower b in front of the spring. The knife-holder B serves as a socket for the kn ifesheath C, which sets into it and is held in place by a nut c, which engages with the threads 5 upon the exterior of the outer end of the knifeholder B.

The knife-sheath is hollow and contains a knife D pivoted therein. This knife has a projecting heel d, which is in position to be 7 engaged by the follower 6, this heel (Z projecting above and rearward of the pivot cl of the knife. The upper side of the knife-sheath C is slotted lengthwise with a slot 0 sufliciently wide to allow the knife to pass up 75 through it. The knife D, as shown, has three blades (Z and its free end has an upwardlyprojecting toe (1 by means of which the knifeblades d are brought into use in the following manner: In the end of the knife-sheath Q C is a diaphragm d, through which passes a rod 6, having an enlargement 6, adapted to engage the under side of the toe 0Z The rod 6 has about it a spiral spring 6 and its further end is connected to a connection 0 set- 5 ting in the handle E, which is pivoted to a bracket F, attached to the side frame F, this construction being such that-upon pushing in the handle E the knife is thrown up by the engagement of the portion 6 with the toe d 9 so that the knife D is thrown up through the slot in the knife-sheath and its blades d are forced into the inner surface of the cop-tube. This action also causes the follower b to be pushed back by the heel (Z of the knife against the force of the spring 7). Upon the release of the handle E the spring 6 tends to throw down the knife into the position shown in Fig. 1, and the spring a throws the handle back into its original position, also shown in Fig. l. The spindle A is in rotation during this operation, and it is necessary that the cops G shall be held from turning in order that the knifeblades may encircle the interior of the coptube G, and so separate the cop-tube into its proper number of parts. For this purpose there is shown in Fig. 2 a convenient form of grip for holding the cop, which grip consists merely of two jaws H of proper size and shape, which are hinged together at it, as shown in Fig. 2, so that the operator after putting the cop upon the knife sheath and pushing it home against a suitable stop, such as D, (which is merely a collar attached to the sheath by a set-screw D applies the grip to the cop, holds the cop tightly, and pushes in the handle E. The knife-blades immediately enter the cop-tube and as they revolve with the sheath cut the cop-tube in the manner described into four lengths, one for each cop G, the knives being properly located for this purpose. The blade 1) may be removed to substitute another knife having a different number of knives thereon to correspond with the number of cuts needed.

W hat I claim as my invention is 1. A cop-tube-cutting mechanism consisting in a rotary spindle adapted to receive a cop-tube, a bearing for said spindle, means whereby said spindle is rotated in said bearing, said spindle carrying within it a knife normally sheathed, and means whereby said knife is thrown into engagement with said cop-tube, as and for the purposes described.
